The National Information Standards Organization (NISO) has announced the publication of a new recommended practice, Demand Driven Acquisition of Monographs (NISO RP-20-2014). Demand driven acquisition (DDA), also referred to as patron-driven acquisition, is a method used by libraries for collection development where monographs are purchased at their point of need when selected by users from a pool of potential titles.
NISO's Recommended Practice discusses and makes recommendations for publishers, vendors, aggregators, and libraries about key aspects of DDA, goals and objectives of a DDA program, choosing parameters of the program, profiling options, managing MARC records for DDA, removing materials from the consideration pool, assessment of the program, providing long-term access to un-owned content, consortial considerations for DDA, and public library DDA. Although DDA is more commonly used for e-books, the method can also be applied to print publications and these recommendations provide a single set of best practices for both formats, with articulation of differences where they occur.
Demand Driven Acquisition of Monographs (NISO RP-20-2014) is available for free download from the Demand-Driven Acquisition Working Group webpage on the NISO website at: www.niso.org/workrooms/dda/.
